Cycling is taken into account when the Dutch undertake large
infrastructure projects. Nijmegen now has a third bridge over the river
Waal and it has a smooth wide cycle path. The bridge is named ‘The
Crossing’ (De Oversteek) after a heroic military action in World War II and it was opened on 24 November 2013.
The river Waal formed the north border of the city for 2000 years, but
that is now changing. Nijmegen’s first bridge was the 1879 railway bridge. In 1936 the first traffic bridge
was completed. Both these bridges can also be used for cycling. In the
case of the railway bridge on the now 10-year-old cycle bridge attached
to it (the ‘Snelbinder’).
This new third bridge is part of a much larger project, that involves
water management and a large-scale city expansion north of the river in
the former village of Lent. As a measure to prevent flooding, the government of The Netherlands is
changing the course of the river Waal at Nijmegen. The Nijmegen project
is in itself again also part of a much larger project called ‘Room for the River’ in which more than 30 rivers throughout the country are being altered. Read much more here.

Recently Strava released a global heatmap of 77,688,848 bicycle rides and 19,660,163 runs from the Strava
dataset. This was more of an engineering challenge to create a
visualization of that size than anything else. Last year the code was cleaned up and became the Personal Heatmaps feature on Strava. This time it has been refactored to handle the large dataset by reading from mmapped files stored on disk. To start out, the world is broken up into regions presented by zoom level 8 tiles. Each one of these regions has a file containing the sorted set of key/values where the key is the pixel zoom and quadkey
and the value is the count of GPS points. The quadkeys make it so all
the data for a tile is stored sequentially in the file. Pixels with no
GPS points are excluded and only every 3rd zoom level is stored in the
file. The values for missing zooms can be found by adding the 4 to 16
values from higher zoom levels. Skipping zoom levels saves a bit a disk
space, but it also preloads into memory the region of the file needed
for deeper zooms. Well, if this is all way too technical, then go to this page and start playing.

The city of Milan, one of the most car-dependent in Europe, is also
among the few to have introduced a road pricing measure. Unlike the well-known cases of London and Stockholm, it was concern
for the levels of pollution (rather than congestion) that initially led
to the introduction of the ‘Ecopass’ scheme in 2008. In the following
years, public debate focused on the effectiveness of this pollution
charge in reducing PM10, a pollutant with adverse health impacts. The dubious effectiveness of Ecopass in reducing PM10 levels has had
two consequences: First, the scheme was upgraded to a congestion charge
in 2012, following the results of a city-wide referendum in which 79.1%
of voters demanded both an upgrade and an extension of the Ecopass area.
This was in stark contrast with the experience of other cities, where
voters have rejected charging schemes, for instance in Edinburgh or
Manchester in the UK. The new city administration has recently implemented a
monitoring system for Black Carbon, a new PM metric that is more
suitable to prove the effectiveness of traffic restrictions. Milan therefore is the only city which can boast two types of road
pricing measures, pollution charge and congestion charge. Read more here.

The prevalence of bicycles in a community is an indicator of our
ability to provide affordable transportation, lower traffic congestion,
reduce air pollution, increase mobility, and provide exercise to the world’s growing population. Bike-sharing programs are one way to get cycles to the masses. In early 2014, some 600 cities in 52 countries host advanced
bike-sharing programs, with a combined fleet of more than 570,000
bicycles.Spain leads the world with 132 separate bike-share programs. Italy has 104, and Germany, 43. The world’s largest bike-sharing program is in Wuhan, China’s sixth largest city, with 9 million people and 90,000 shared bikes.In 2013, China was home to 82 bike-sharing programs, with a whopping combined fleet of some 380,000 bicycles.The United States hosts 36 modern bike-sharing programs.
With a number of new programs in the works and planned expansions of
existing programs, the U.S. fleet is set to nearly double to over 37,000
publicly shared bicycles by the end of 2014. Read more on the website of the Earth Policy Institute here.

Today Zwolle was announced to be the winner of the title “Best Cycling City of the Netherlands in 2014″! This week the magazine of the Cyclists’ Union gave spokesperson Hans Hop of the local chapter of the Union some
phrases with regard to cycling in Zwolle, to which he responded as
follows. Biggest challenge? “The lack of bicycle parking facilities, especially in the city
centre and the station. Greatest improvement? “The many innovations, such as good bicycle tunnels, traffic light
waiting time indicators and the bicycle roundabout. What is the effect of the Best Cycling City Election ? “This election is great because it draws attention to a lot of
things. Wishes? “There are always areas to improve. For instance we think that
bicycle signage could be better. We also advocate for bicycle facilities
around larger stores. Zwolle will get a new Ikea, a new Hornbach and a
new Zara. Developers forget the bike all the time. The municipality can
make sure they do keep cycling in mind in the planning phase. And we
would like new paths to be wider. You need to anticipate that there will
be more people cycling in the future”. Read on In Bicycle Dutch here.

The cycle highway from Hattem to Zwolle was festively opened
by a class of schoolchildren, the alderman for traffic of the city of
Zwolle and a representative of the province of Overijssel on November
first of 2012. It was the third part of the entire route. The first part
consists of ordinary cycling infrastructure from Hattem to a new
railroad bridge. The second part is that railroad bridge over the river
IJssel that got a cycle path hanging from one side of it. The cycle path
on the bridge was already opened in June 2011. But with that third part
the total fast cycle route was completed. It means people can now cycle
the entire 5.5 kilometre route from Hattem in the province of
Gelderland to Zwolle, the capital of the province of Overijssel at high
speed away from motor traffic.The 5.5 metre wide fast cycle route from Hattem to Zwolle in the city of Zwolle. The route has almost no intersections and there are no traffic
lights. Cyclists have priority all the way and that makes this route a
fast and viable alternative to the car. The route for motor traffic is
also almost one kilometer longer. The fast cycle route is an attractive
and quick route to Zwolle’s central railway station but it can also be
used to reach several schools and a commercial area. Read on here. The beauty in the video starts at 5'45" Thanks again Bicycle Dutch.
